Abstract

An optically trapped particle works as an extremely sensitive probe for the measurement of pico-and femto-Newton forces in microscopic systems (photonic force microscopy, PFM). It comprises an optical trap to hold the probe particle and a position sensing system. The backscattered light field projected on a quadrant photon detector (QPD) or a position sensitive detector (PSD) to monitor the position of the particle.
